Output Drive Strength

The DC drive strength of the individual clock output can be

programmed for different values. Table 3 shows the typical rise

and fall times for different drive strength settings.

Generic Configuration and Custom Frequency

There is a generic set of output frequencies available from the

factory that can be used for the device evaluation purposes. The

device, CY2545/CY2547 can be custom programmed to any

desired frequencies and listed features. For customer specific

programming and I2C programmable memory bitmap definitions,

please contact your local Cypress Field Application Engineer

(FAE) or sales representative.
